Limited (“Parent”), Yongye International Merger Sub Limited (“Merger Sub”) and the Company (the “Merger

holders of at least a majority of the issued and outstanding Shares (other than the Excluded Shares) that are present in person
or by proxy and voting for or against approval of the Amended Merger Agreement at the stockholders’ meeting.

The
Amendment provides for an increase in the maximum amount of the Company’s expenses in connection with the transactions contemplated

The Amendment also extends the termination
date from June 23, 2014 to September 22, 2014 such that, subject to certain conditions, the Amended Merger Agreement may be terminated
and the Merger may be abandoned by either the Company (upon the approval of the special committee of the Company’s Board
of Directors (the “Special Committee”)) or Parent if the proposed Merger is not consummated on or before September
22, 2014.

Other than as expressly modified pursuant to the Amendment,
the Merger Agreement, which was filed as Exhibit 2.1 to the Current Report on Form 8-K filed with the Securities and Exchange Commission
by the Company on September 23, 2013, remains in full force and effect as originally executed on September 23, 2013. The foregoing

in its entirety by, the full text of the Amendment, attached hereto as Exhibit 2.1 to this Current Report on Form 8-K, which is
incorporated herein by this reference.
